An American television producer found dead on a hotel balcony in Uganda last week died after taking contaminated cocaine, police and a private investigator said on Saturday.

An official toxicology report confirmed the narcotic was in Jeff Rice's blood, dispelling initial suspicions the father-of-two known for his work on the U.S. show "The Amazing Race," had been poisoned by attackers.

Rice, who was found slumped over a table bleeding through the nose and mouth, died of asphyxiation, a post mortem showed. Drug users who fall unconscious risk inhaling vomit.
